A model of the Z-10 assault helicopter inside Tiananmen Square in Beijing
Several websites mentioned a video that appeared on China Central Television showing one of the helicopters with "an extra armor module near its tandem cockpit" touch down after a flight. The video has not been independently verified for authenticity, and Beijing is known to keep its military secrets well under wraps.
Previous models of the Z-10 series did not have extra armor due to engine constraints and designers with the state-owned Aviation Industry Corp. of China had to come up with other types of additional protective gear so the helicopter could carry a sufficient payload.
The Z-10 is primarily designed for anti-tank warfare but has secondary air-to-air capability as well. In aerial warfare Z-10s often need to fly low to attack ground targets, making them vulnerable to anti-aircraft fire.
According to various reports, the bottom and sides of the Z-10 cockpit are protected by a composite graphene armor, and so are the engines and the fuel tank in the middle of the fuselage.
